1. Introduction Backgrounds “Tributary protection as a alternative for hydropower development in the mainstream river” is an important environmental protection principle during hydropower develop in China. Notice on strengthening environmental protection during hydropower development (China EPA, [2012] No. 4) The 13th Five-Year Hydropower Development Plan of China (in the period of 2016-2020) approved by National Energy Administration (China NEA) Chinese government needs a easy tool to assessment environmental protection effect at a national scale Our research group is working on the national guidelines for sustainable hydropower SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

1. Introduction Four hydropower plants built on the upstream of the Yangtze River: Wudongde, Maihetan, Xiluodu, and Xiangjiaba Chishui River is an important tributary of the upper Yangtze river Chishui River as a alternative habitat relative to hydropower development in the mainstream of Yangtze River In operation: Wudongde: 10200 MW Baihetan: 16000 MW Under construction: Xiangjiaba: 6400MW Xiluodu: 13860 MW Total: 46460 MW, two times of three gorge hydropower stations SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

1. Introduction Objectives Developing useful tools about how to measure benefits both in a project scale and a watershed scale Quantifying the economic, social and ecological value of Chishui River conservation as a alternative habitat Balancing costs and benefits between Chishui River protection and four hydropower plants in the mainstream of Yangtze River SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

Economic internal rate of return (EIRR) 2. Framework Economic internal rate of return (EIRR) Net economic value Cost and benefit ratio Summarizing benefits (goods and services) in the tributary and mainstream Defining costs of hydropower stations construction and operation, and tributary protection (economic cost) Balancing costs and benefits SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

2. Framework INVEST（Integrated Valuation of Ecosystem Services and Trade-offs）was developed by Stanford University, World Wide Fund, The Nature Conservancy. Providing scientific information for policy makers to weigh the benefits and impacts of human activities among different scenarios. A B Providing distribution of benefits of ecosystem goods and services. Integrating the value of ecosystem services into decision-making and operational management of hydropower stations SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

2. Framework The change of habitat quality index in chishui river basin from 1980 to 2015 based on the InVEST model SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY

3. Investigation The index of biological integrity (IBI) : An indicator aquatic ecosystem health to assess biology assemblages Overcome the limitations of chemical and physical parameters in the assessment of aquatic ecosystem health A sensitive indicator in the assessment of aquatic ecosystem health degradation associated with cascading dams Capture aquatic trophic status and identify variations in aquatic ecosystem health and degradation SYDNEY, AUSTRALIA | 14 -18 October 2018 MANAGED BY
